LINE-FASTEIN ER.

SPECIFICATION forming part of Letters Patent'No. 521,847, dated June 26,1894.

Application filed $eptember29,1893- Serial No. 486,813. on model.)

To all whom it may concern.-

Be it known that I, RICHARD MARTIN CHRISTENSEN, a citizen of the UnitedStates, residing in the city and county of New York, State of New York,have invented a new and useful Device for Fastening the Ends of Lines orCords, of which the following is a specification. 7

My invention relates to line grippers or fasteners, the object being toprovide a de; vice of this character by means of which the meeting endsof a line may be secured together by a simple process and at the sametime be so adjusted that they may be readily loosened for the purpose oflengthening the line or entirely separating its ends.

With these objects in view the device consists of a fastening blockhaving two parallel holes through which the ends of therope pass inopposite directions. One side of the block is provided with an obliquekerf or slit which partially crosses one of the rope passages.

, When the rope is drawn up to the proper length or (adj ustmentrequired, the free end is passed into this'oblique kerf and drawn towardthe inner extremity thereof, where it becomes grippedby the sides of thekerf itself and also by the pressure of the corresponding end of therope against it.

The details of the invention will be fully described with reference tothe accompanying drawings, in which- Figure 1 is a longitudinal sectionof the fastening block. Fig. 2'is a side elevation of the same with theends of the rope in place. Fig. 3 is a plan of the device, and Figs.tand 5 are respectively side and end views of 'a modified form of thedevice.

Referring to the drawings, it will be seen that the block itself is anelongated structure having two parallel holes or passages O 0' runningthrough it from end to end. One side of the block is provided with anoblique kerf, slit or opening B which extends from a point on the sidenear one end of the block obliquely inward toward the other end andintercepts or crosses one of the passages, C. This opening forms atongue A and the inner end of the opening gradually contracts into awedge or V shape. This opening 13 at some a straight line.

the location where it coincides with the pass sage 0 makes the latterwider or forms a slight bulge in it so that a rope, when passed throughit, may be forced into the bulge, slightly out of a straight line. Whenthe block is made of wood orother comparatively weak material theopening B makes a weak spot at one end of 'the block which may bestrengthened by a metallic band or-strap a. When the block is made ofmetal this is unnecessary.

The rope is represented by D. The two ends of it respectively pass inopposite directions through the passages O O. which passes through thepassage 0, is held in place bya knot which, being larger than thediameter of the passage 0, prevents the rope from being pulled through.The other end of the rope passes through the passage 0 and is pulled upuntil the desired length or adjustment of the rope is obtained. Then itisbent over the block, passed through the opening B and pulled downtight into the inner end thereof where it becomes wedged in or grippedby the wedge shaped end of the opening and by the other end of the ropelying therein. Then the freeend of the rope is thus forced into theopening, the fixed end is thrown over into the bulge caused by theopening B and thereby forced out of a straight line. Hence when tensionis put upon the line the grip upon the free end of the rope iscorrespondingly increased by the tendency of the fixed end of the sameto as- To release the rope it is only necessary to lift the free end outof the opening 13 and this may be done without drawing up slack on theline.

In Figs. 4 and 5 the form when constructed of metal is illustrated.Instead of the two continuous passages O C','guide eyes 0" O areprovided; these hold the rope in astraight line in about the same manneras the continuous passages do, but it is to be understood that in theclaims whichfollow the guide eyes are the equivalents'of the continuouspassages.

described my invention, I

The end block having two passages through which the directions andhaving an oblique kerf or slit [0 ends of the rope pass in oppositedirections, entering the side of the block and interceptand an obliqueopening intercepting one of ing one of the passages, said slit havingconsaid passages into which a free end of the tracting sides betweenwhich both ends of a 5 rope is passed to become gripped by the otherrope are clamped one against the other.

which the ends of the line pass in opposite JESSIE S. HIRSEMAN.
